If it went to a MINI dealer for the repair of the bumper, and the new owner ever takes it to the dealer, the new owner will find out about it, anyway.
And if it really was a bump, then there's no big deal about telling. You bumped it, it wasn't bad enough to set off the airbags, you repaired it, dealer can confirm it. Be upfront about it and the person will know you're not trying to hide anything else. |
